I wasn’t very charitable with my interpretation there, you’re right incentivizing more people to walk is definitely a good a thing.
I think a lot of the smartwatches have done a decent job at that, though there of course is the overhead to buy and wear one of them.
But even as someone who has been getting daily exercise for at least a decade now and doesn’t need encouragement, the little awards my Apple Watch gives me for hitting my targets feels good.
